It means that you should always try to continue speaking and not just suddenly stop talking.The examiner wants to evaluate your speaking skills,so just try to keep talking, and not have any long silences.The examiner (if you mean the IELTS exam) cannot say anything during your monologue,you MUST fill up the allotted time,so just try to prepare enough to say that there will not suddenly be a long pause.

If you're having a conversation with someone avoid dead end questions. You'll want have the person elaborate on whatever is asked. Don't let the conversation die out with yes or no answers and questions.

Find a good partner and try to make conversation every day. the more you practice the longer and fluently you speak.

As well as Peter's advice on "advice" (it's uncountable, and treated as singular), remember that "I" (as in me, myself) is always a capital letter. For keeping a conversation going, get the other person to do the speaking. ;) One way of doing this is to ask "open-ended" questions. For example, "Did you eat breakfast?" only has two answers: yes or no. No good. "What did you eat for breakfast?" is a little better, but the answers are still limited. An open-ended question would be, "How important is breakfast to you?" However, if your conversation partner is also the examiner, then you need a different tactic. :)
